2400 BPS Internal Modem (250-1037) Installation Faxback Doc. # 4695 INSTALLATION IN YOUR COMPUTER The modem is designed for easy installation in any compatible computer. Because of its small size, the modem will fit in both short and standard- length expansion slots. 1. Power to the computer must be turned off before proceeding with the rest of the installation. Refer to the computer owner's manual for informat- ion on turning off the computer. WARNING: To avoid static electricity buildup, which can destroy certain integrated circuits, touch a grounded metal object (such as the computer chassis) while handling any circuit board. Do not stand on a carpeted floor while installing this board. 2. After the computer is turned off, remove the screws securing the computer's cover, and slide the cover to open the computer. Save these screws so that you can replace the computer's cover at the end of installation. Refer to the computer owner's manual for more information on removing the computer's cover. 3. The modem board fits in a half-card expansion slot, but it may be installed in a full-card slot if desired. Decide which expansion slot you want to install your modem in. To remove the expansion slot's rear panel blank card bracket, remove its fastening screw and lift the bracket straight up. Save the screw for attaching the modem board later. 4. Plug the modem board into the empty expansion slot. Then, fasten the board to the computer using the screw that was removed from the blank card bracket. 5. Replace the computer's cover, securing it with the screws which were previously removed. 6. There are two modular phone connectors on the modem. Connect one end of the modular phone cable supplied with the modem to either of the two jacks. The jacks are identical; it does not matter which one you use. Connect the other end of this modular cable to the phone jack on your wall. NOTE: You can connect your standard telephone to the second jack on the back of the modem. This jack is provided your convenience so that you can continue to use your telephone normally. As long as you leave your modem and phone connected, you can continue to use your telephone even when your computer is turned off. (smm 07/28/93)
